They say there's no better friend than a sister - and for a new breed of power sisters, they share more than just friendship.
The likes of Kendall and Kylie Jenner, Bella and Gigi Hadid and Suki and Immy Waterhouse share fame, fortune, A-list contacts and fashion kudos with their sisters.

With a powerful sisterly sidekick comes a better reputation, double the power and, of course, a boost to the bank balance. FEMAIL examines the rise of the power sisters in young Hollywood.

KENDALL AND KYLIE JENNER
COMBINED REPORTED NET WORTH: £4.9m
COMBINED INSTAGRAM FOLLOWERS: 76.1M
They may only be 19 and 18 respectively but Kendall and Kylie Jenner are already making a name for themselves as two of the globe's most powerful sisters.
As the youngest of the Kardashian clan, Kylie, was thrust into the spotlight at an impressionable age. But, as her burgeoning career proves, she's handled it just fine - and is already worth a reported $5m (£3.23m).
Kylie was recently unveiled as the ambassador for beauty brand Nip + Fab, which is the latest in a string of successes for the young star, who recently landed herself a shoot in the highly acclaimed fashion bible, Carine Roitfeld's Fashion Book.
When Kanye West, who is married to her older sister Kim, debuted his first solo collection in New York last month, it was Kylie who he asked to star in his show.
More experimental than her sisters in Keeping Up With The Kardashians, Kylie regularly posts pictures of herself trying out different make-up and hairstyles on her Instagram account and received such a positive response from fans that she went on to launch her own beauty website.
The Keeping Up With The Kardashians star bought her very own place in Calabasas, Calif., in February for £1.74m ($2.7 million), and has decorated it in a glamorous style befitting the teen's taste.
Kylie already has her own array of vehicles - including a white Range Rover and Rolls Royce Ghost - but she got the best surprise ever on her 18th birthday when her boyfriend, Tyga, gifted her with a $320,000 white Ferrari 482 Italia.

She and Kendall also have their own clothing and shoe range stocked in Topshop and brands are clambering over each other to tap into Kylie's magic.
Kendall has also seen her star sky-rocket in the past year. She started out on the E! show that propelled her family to global fame as the shyest sibling - avid fans will remember when she was too nervous to interview people on the street for her Teen Vogue column.
But fast-forward a few years and she's the coolest Kardashian/Jenner export.
It has been her lifelong dream to break away from the show that propelled her to fame and cement her name as a model - and now Kendall is making her fantasy a reality.

Since then, the brunette has starred in campaigns for the likes of Givenchy, Estée Lauder, Marc Jacobs, Fendi, Calvin Klein and Balmain.
By Spring 2014, she was walking in Fashion Weeks in New York for Marc Jacobs, London for Giles Deacon, and Paris for Givenchy and Chanel.
Her close friendships with top designers have meant major names have hand-picked her for their shows, with Karl Lagerfeld choosing the teen as his 'bride' in his Paris Haute Couture Fashion Week show in July.
The star proved she ranks up there with some of the best-known supermodels in the world after she entered Forbes' list of highest-paid models for the first time.
The reality TV star is the youngest model on the list, with her $4million (£2.63m) earnings putting her just behind Kate Moss.
Kendall places eighth on Forbes' 2015 list, and while Gisele Bundchen's $44million earnings dwarf the rest of the top ten, the rising star matches some much more established models with her bank balance.
Before she broke into the fashion industry, the majority of Kendall's salary came from Keeping Up With The Kardashians, with her and Kylie reportedly making around £9,800 ($15,000) per episode.
Other forms of income come from her and Kylie's clothing brand, Pac Sun, as well as their young adult book Rebels: City of Indra, which is based on two young girls Lex and Livia, who embark on a journey together, but later realise their biggest danger might be each other.
Plus, Kendall has very carefully selected her friends and certainly runs with the in crowd, dubbed Hollywood's new brat pack.
From hanging out with her uber famous sisters; Kim, Khloe, Kourtney and Kylie, to kicking back with some of the most famous stars on the planet, Kendall is not only close friends with Justin Bieber, she's also been spotted hanging out with Selena Gomez, Taylor Swift and Jaden Smith.
The independent star is clearly doing well; she has her own two-bedroom £890,000 ($1.4m) luxury high-rise condo on The Wilshire Corridor near Beverly Hills.
According to TMZ, Kendall bought the condo in May 2014 through Kyle Richards' daughter, Farrah, who works with real estate agent Mauricio Umansky at The Agency.
The pad has high ceilings, white walls and wood floors. The building has a 24-hour valet, a concierge and doorman, heated pool, fitness center, catering kitchen, social room, card room and wine storage. The property is usually vacant, however, as Kendall spends most of her time in New York City.
It probably doesn't hurt that the second youngest of the Kardashian clan has a cool 38 million Instagram followers.
GIGI AND BELLA HADID
COMBINED INSTAGRAM FOLLOWERS: 8.2M
From being named as the face of Topshop, to landing herself campaigns with American super-brands Guess, Seafolly and Maybelline, Gigi has been making serious waves in the modelling industry.
Her net worth, which is an estimated £300,000, according to Celebrity Net Worth, isn't yet reflective of some of her newer campaigns - and she looks set to get even bigger and wealthier in the coming months.
Of course, she has all the makings of a supermodel, and it's not just about her obvious good looks and jet-setting lifestyle. Gigi's mother, Yolanda Foster, stars on Real Housewives of Beverly Hills, her father is Palestinian Architect Mohammed Hadid, who is a multi-millionaire, and her stepfather is music producer David Foster, who has helped launched the careers of Michael Buble and Celine Dion.
But she's made it all on her own - and proven haters and trolls - who recently slammed her looks - wrong by going on to land some major campaigns.

'I’ve heard from a lot of people in the industry that the supermodel is coming back, which is really exciting for me,' she said recently.
'For a long time you would see a girl for one season and then you’d never really hear about her again. Now models are getting to create a fanbase that keeps them around.'
Gigi, 20, also runs with a seriously cool crowd. She's often spotted hanging out with Cara Delevingne or partying with Justin Bieber and Lewis Hamilton, but her nearest and dearest are Kendall Jenner and Taylor Swift.
Indeed, pop sensation Taylor even called on her pal to star in her colossal Bad Blood video, which Gigi describes as 'absolutely epic'.
Gigi's little sister Bella, 18, may not have had as much exposure as her older sister, but that doesn't mean she has any less potential.
Indeed, Gigi's younger sister is quickly catching up with her star sibling's phenomenal fashion success, carving out an impressive career for herself within the industry.
Her Instagram has an impressive 1.4m followers and is quickly catching up with her sister's 6.8m.
She was recently named as the face of Botkier's spring campaign, and Bella also joined Gigi on the catwalk at the Tom Ford fall/winter 2015 show in February and the Balmain show last week.
Bella was also the star attraction at the Topshop Unique show in London last month and has been landing herself countless glossy magazine spreads.
Bella also launched a clothing line called Robert Riley's, featuring 'simple jeans', 'insane jackets' and 'pieces that genuinely rep [her] style'.

When she's not making her mark on the fashion world, Bella, who is best pals with Victoria's Secret Angel, Stella Maxwell, stays busy with her favorite sport: horseback riding.
According to her official website, the nationally ranked equestrian has been competing since the tender age of three.
One of her life goals is to represent the U.S. in the 2016 Olympics.

She may only be 23 but Suki Waterhouse already has a career that most women can only dream of.
After being scouted in a pub in London when she was 16, the clothes horse went on to model lingerie for Marks and Spencer, as well as starring in Alice + Olivia, Coast and H&M campaigns.
The star has also lent her good looks to Swatch, Lucy in Disguise, Max Studio, Caterina Gatta and Pepe Jeans campaigns.
The supermodel, who counts Kate Moss and Cara Delevingne among her nearest and dearest, was also recently unveiled as the new Global Brand Muse for US hair giant, Redken, Amazon Fashion and Burberry beauty.

Her acting career is burgeoning too, with roles in Love, Rosie, and The Divergent Series: Insurgent. She will also star in The Bad Batch alongside Hollywood stalwarts Jim Carrey and Keanu Reeves.
Suki has been busy partying with her younger doppelganger, Immy, over fashion week - and helping cement her sister as one of the young Hollywood set's freshest faces.
Immy, Suki's 20-year-old sister, is fast following in her footsteps. She made her catwalk debut in the Ashley Williams AW15 show and starred in the Helmer campaign.
She also starred in a modelling campaign for Asda's George's G21 Talent label, a collection of clothing designed by young designers handpicked from Graduate Fashion Week, last June. She has also lent her good looks to campaigns for Urban Outfitters, Coast and Asda.
Clearly keen to follow in her older sister's fashionable footsteps, Immy says that Suki's success has inspired her own career.
'Suki has shown me that hard work pays off and rejection is a big part of it,' she told Vogue.
'Like Suki, I'm not typical height-wise for a model (Immy is 6ft 5) - so she advised me to just forget about those stereotypes.'
